Mine is in for repair, and I'm weighing whether to do the upgrade. Sounds like it will be worth it. I have been using the 39's preamp direct into 334, with astounding results (B&W 804's). Now I am thinking of adding a pre-amp, and wonder if the upgrade should be done on the 39 if I add a 380s. Also considering a tube preamp, possibly the new Mac C2200, as it has a phono stage. I'm not sure if I would run the 39 or 390 direct to 334, or use it through a tubed pre. Any ideas? Probably a 380s with a good tube phono stage might be the way to go for the table. Or would there be a smooth way (short of disconnecting/reconnecting) to use the 390 direct with the balanced output, and rca from tube preamp to the 334?
